Policing a Negotiated World: A Partial Test of Klinger’s Ecological Theory of Policing

Objectives

Klinger’s (Criminology 35(2): 277–306, 1997) ecological theory of policing addresses the intersection of environment and police organizational structure on police patrol practices. The current study addresses the following question: ‘Is police response to calls for service influenced by the level of serious violent crime or the level of officer staffing?’

Methods

This question was addressed using crime, incident, and staffing data supplied by the Philadelphia Police Department. The dependent variable was the number of unfounded events per month, per police district, from 2004 to 2008. Analysis controlled for linear and non-linear trends, average monthly temperature, month length, and spatial effects. Data were analyzed using repeated measures multilevel modeling.

Results

Findings suggested that the quantity of unfounded events was associated with both workload and officer staffing levels. Consistent with theoretical predictions, higher workload was associated with more unfounded incidents while higher levels of officer staffing was associated with fewer unfounded incidents, net of ongoing trends and spatial effects.

Conclusions

These findings are consistent with the Ecological Theory of Policing and suggest that officers may shed workload in response to higher demands for service or lower levels of officer availability.

     

Solution-Focused Trauma-Informed Care (SF-TIC): An Integration of Models

Trauma-informed care is a rapidly emerging approach in child welfare and is significantly aligned with the core tenets and techniques of solution-focused practice. The integration of solution-focused practices and trauma-informed care offers an alternative to the problem-solving method frequently employed in child welfare. This paper describes and demonstrates how using a Solution-Focused Trauma-Informed Care (SF-TIC) approach can shift individuals and systems from a problem-solving focus to solution building. SF-TIC provides individuals with concrete skills, language and knowledge to effectively avoid inadvertent re-traumatization. Evaluation of this approach is in its infancy and future research is warranted.     

Parental efficacy, self-control, and delinquency: A test of a general theory of crime on a nationally representative sample of youth

Criminologists have recently begun examining Gottfredson and Hirschi's (1990) proposition that parenting is the primary influence on children's levels of self-control. The few existing studies on the subject, however, have typically been based on small, nonrandom samples. The current study examines the relationships between parental efficacy, self-control, and delinquent behavior using data from a nationally representative sample of adolescents (the National Longitudinal Study of Adolescent Health). The results indicate that although parental efficacy is an important precursor to self-control, contrary to Gottfredson and Hirschi's proposition, self-control does not completely mediate the relationship between parental efficacy and delinquency. The implications for future research and theoretical development are discussed.     

Cognitive ability and delinquent behavior among inner-city youth: a life-course analysis of main,mediating, and interaction effects

Drawing on the emerging life-course paradigm in criminological theory, this study examines the relationship between cognitive ability and delinquent behavior within a sample of inner-city youth. The results indicate that net of statistical controls, cognitive ability maintains a robust inverse relationship with the likelihood of the onset of delinquency, the early onset of delinquency, and the persistence of delinquency during the 18-year period covered by the dataset. Furthermore, cognitive ability mediates the effect of concentrated disadvantage on both the onset and early onset of delinquency. Overall, the results of this study suggest that cognitive ability is an important criminogenic risk factor that has important implications for both correctional interventions and the continued development of structural and multilevel theories of crime.     

Social support and homicide: a cross-national test of an emerging criminological theory

The social support (also known as social altruism) perspective in criminological theory has emerged as a potentially important explanation of aggregate levels of crime. Recent studies have tested the theory's ability to predict levels of violent and property crimes at the city and state levels in the United States, yet a formal test of the theory using data from outside of the U.S. has yet to be conducted. Accordingly, this article draws on insights from social support theory in a cross-national context. Consistent with the core proposition of the theory, the analyses show that, net of statistical controls, the indicator of social support is inversely and significantly related to rates of violent crime (measured by homicides). The implications of these results for criminological theory development and for the construction of effective crime control policies are discussed.
